The DSR makes it possible for product programmers to develop toothpaste with the ideal uniformity so that it can be squeezed from a tube however not drop off the tooth brush. The DSR examinations binder put in between 2 identical plates about the size of a quarter. One of the plates relocations and the maker measures the viscoelastic residential properties of the asphalt.
